[1] Emperor Stefan Dušan sent Palaiologos a cavalry force of 4,000[1] or 6,000[2] under the command of Gradislav Borilović[3][2] while Orhan provided Kantakouzenos 10,000 horsemen.

[1] Also Bulgarian tsar Ivan Alexander sent an unknown number of troops to support Palaiologos and Dušan.

[4] The more numerous Ottomans decisively defeated the Serbs and Bulgarians, and Kantakouzenos retained power, while Palaiologos fled to Venetian Tenedos.

[4] According to Kantakouzenos about 7,000 Serbs fell at the battle (deemed exaggerated), while Nikephoros Gregoras (1295–1360) gave the number as 4,000.

[3] The battle was the first major battle of the Ottomans on European soil, and it made Stefan Dušan realize the major threat of the Ottomans to Eastern Europe.
